Systems and methods for debugging in a multiprocessor environment

A method, system and apparatus for debugging in a multiprocessor environment. The system includes a principal processor which remotely debugs target programs running on a plurality of different target processors. The different types of target processors differ with respect to their instruction sets. The principal processor debugs the target programs and is configured to provide a plurality of debugging instructions specific to each instruction set, determine the type of target processor executing a target program to be debugged, select among the debugging instructions specific to each instruction set based upon the identified type of target processor, and insert the selected debugging instructions into the target program.
